Corrective Action
This procedure details the corrective action for clearing the SSFODUEGR declared on an
OT port. At the end of each step wait to see if the fault clears. If not, continue with the
next step.
...................................................................................................................................................................................................
1
Retrieve power level reading on the local OT port.
...................................................................................................................................................................................................
2
If power level is low on the DWDM facing port, identify the associated OCh trail and
verify the power levels along the OCh trail.
...................................................................................................................................................................................................
3
Identify the farthest upstream point relative to the far end OTUk port at which power
level falls within the expected range.
...................................................................................................................................................................................................
4
Check the alarms/conditions on the node located in Step 3 or the node immediately
upstream from point identified in Step 3.
...................................................................................................................................................................................................
5
Correct the problem identified in Step 4.
...................................................................................................................................................................................................
6
If all power levels along the OCh trails fall within the target range, locate the fiber
connected directly to receiver of the port which detects SSFODUEGR condition.
...................................................................................................................................................................................................
7
Clean the fiber.
...................................................................................................................................................................................................
8
If cleaning the fiber does not clear the problem, replace the fiber.
...................................................................................................................................................................................................
9
If the problem is detected on the client port of OT, and the power level is within the
operating range, check for pluggable module alarms.
...................................................................................................................................................................................................
10
Replace the pluggable module.
